Trim the stalks from the plant before they begin producing flowers. Chives lose their flavor after flowering.
Cut chives into 1/4- to 1/2-inch long pieces. Whole chives stalks also dry well but have less culinary uses.
Line a baking sheet with parchment paper. Spread the prepared chives out on the paper in a single layer.
Place the tray in a well-ventilated location away from direct sunlight, either outside or indoors. Stir the chives once daily so they dry evenly.
Package the chives in an airtight container once they dry completely and become brittle. Chives take approximately 10 hours to dry outdoors or one to three days indoors.
